Okay, so I decided to start again from the beginning since I got hung up on the floor 7 boss, likely due in part to having screwed up builds.
I started playing it long before I found this thread, just to let you guys know.
So, I did some grinding on floor 2 so I could beat Chen and Meiling.
Right now my team is as follows.
Reimu = HP/MND/DEF
Marisa = Pure MAG
Patchy = MAG/MND
Sakuya = Heavy ATK/Moderate DEF
Remilia = Same as Sakuya, but more, and with decent HP too.
Chen = Heavy ATK, Moderate SPD
Meiling = Heavy HP/DEF, Moderate MND
So here's what I'm asking, who should go where, now that I have Chen and Meiling?
My normal lineup is like this.
Remi = Slot 1
Reimu = Slot 2
Sakuya = Slot 3
Marisa = Slot 4
And Patchy, Chen, and Meiling are chilling in backup until I can figure out what to do with 'em.
I can't even handle a lone Peg Insect yet. I'm around Lv7-10, and only just recently recruited Chen and Meiling as of this post.
When I fought Chen, Remi's gungnirs(unbuffed, didn't want to risk it) were dinging her for 700+, and Marisa's Magic Missile(no spark yet, only 139 SP) was hitting 500+, despite me having sunk all her levels into MAG, and sunk a fair bit of skillpoints into it too, enough to get it to Lv10. Sakuya was hitting comparble to Remi with Killer Doll, and Reimu was giving buffs the whole time, didn't even need to heal with Remi, Reimu, and Sakuya being pretty tanky, thanks to buffs and build.
Even on floor 2, Patchy's Royal Flare can hit upwards of 1k+, most it's ever dealt was around 14xx.
So basically, Reimu's a slot 2 tank, Remi's the main tank/off nuker, Sakuya's whatever I need at the time, and Marisa's just a Nuker, like she always is.
